  • Patent number: 3947233
    Abstract: There is disclosed a free-burning equipment for gaseous fuel which comprises a burner member or filter into which fuel is fed under pressure by a feed pipe. The burner member is suitably shaped such as a flat plate which includes a multitude of narrow channels for the passage of fuel therethrough. The fuel is mixed as it turbulently emerges from the outside of the burner member, and is later ignited. A multitude of flames will thus, due to the gas pressure, burn well away from the burner head surface permitting said burner head surface to remain cold during so-called "free-burning.
